Towards zero shot learning of geometry of motion streams and its application to anomaly recognition

作者:

Highlights:

• Geometry of temporal-derivatives contains discriminatory features.

• Late fusion of temporal-derivatives declines recognition performance.

• Local anomalies have lower recognition rates than global.

• Variation in temporal scales requires spatial–temporal fusion.

• Deep flow has stronger priors than foreground segmentation.
